Abstract

The invention discloses a base-station radio-frequency testing system applicable to an LTE (Long Term Evolution) system and a testing method. The base-station radio-frequency testing system is connected with a base station to be tested and is used for testing radio-frequency data of the base station to be tested. The base-station radio-frequency testing system comprises a frequency-spectrum analyzer, a channel simulator, a useful signal generator, an interference signal generator, a broadband signal generator, a power meter, a main control computer and a radio-frequency box, wherein the main control computer is connected with the frequency-spectrum analyzer, the channel simulator, the useful signal generator, the interference signal generator, the broadband signal generator, the power meter and the radio-frequency box; the radio-frequency box is connected with the frequency-spectrum analyzer, the channel simulator, the useful signal generator, the interference signal generator, the broadband signal generator, the power meter and the base station to be tested; the power meter is connected with the broadband signal generator; the radio-frequency box comprises a switch, a load, an isolator, a coupler, an attenuator, a combiner, a multi-frequency combiner and a radio-frequency interface.

Description

Technical field [0001] The present invention relates to the field of mobile communication, in particular to a base station radio frequency test system and test method suitable for an LTE system. Background technique [0002] LTE is one of the mainstream technologies for fourth-generation mobile communications. It supports FDD (Frequency Division Duplex) and TDD (Time Division Duplex) modes. TD-LTE is a time division duplex LTE system, and LTE-FDD is a frequency division duplex LTE system. At present, the commercialization of LTE systems has received the most extensive attention from global operators and equipment vendors. Therefore, the base station equipment is an important network element in the communication network, and its performance determines the quality of the entire system. [0003] In the prior art, the system for the base station radio frequency test of the LTE system is complicated to build, and the manual construction of the test system is easy to introduce unneces...
